. Application filed October 13, 1880. (No model.) Patented in EnglandJanuary 21, 1876. and Decemherl l, 1876.

To all whom it may concern Be it known that we, JoHN MUIR HETHER-lNGTON, of Manchester, in the county of Lancaster, En gland, and EDOUARDJ ULES JOSEPH LEOCEUR. of Rouen, France, have invented a newand usefulImprovement in Oombing-Machines; and we do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accom- 1o panying drawings, forming part of thisspecification, in which- Figure 1 represents a sectional elevation of amachine containing our inventions; Fig. l a plan view of the same; Figs.2 to 7, detail 1 5 drawings of the successive positions of the nippers;Fig. 8, a vertical longitudinal section of the cylinder 5 Fig. 9,avertical transverse section of the same; Figs. to 13, verticallongitudinal sections of the cylinder, pusher, holder, table, anddelivery-rollers in different posi tions, as in course of operation.Fig. 14 represents a vertical transverse section of the cylinder andwheels attached thereto. Fig. 15 shows an elevation of the same. Fig. 16is a detail drawing of the cams attached to the driving-shaft and thelovers working thereon. Figs. 17 and 18 show plan and elevations of theworking mechanism of the cylinder-jaws. Figs. 19 and 20 represent detailviews of the 0 construction, and show the mode of operation of thecylinder-jaws.

Our improvements relate to machines for combing cotton and other fibrousmaterial.

The object of our invention isto construct a 5 machine which shall moreeffectually comb cotton or other fibrous material than has hitherto beenpossible.

Our invention consists, first, in a particular construction of therotating clamps; second, in a comb situated on or near the feed-plate,operating in connection with the aforesaid clamps; third, in a combfastened on a lever and having a reciprocal and oblique movement;fourth,in a pusher havingaforwardand down- 5 ward movement and a holderhaving a vertical movement, in combination with a tablefor receiving andpiecing together in slivers the tufts of fibrous material; and, finally,in certain details of construction, all of which will be hereinaftermore fully described.

In order that a clear comprehension of the mechanism may be had, suchparts as are not necessarily dependent for operation upon theirconnection with the peculiar combination of mechanism employed will bemerely adverted to in a general way and their exact connection with theelements of the invention will not be consecutively traced out.

The cotton, wool, or other fibrous material, after passing over therollers D D, is received in a trough, l, curved at the upper end anddescending obliquely in a forward direction toward the curved plate 2,supported in any convenient way upon the frame-work of the machine.

3 is a roller, designed to feed at intervals the material to be operatedupon to the nippers 5 6. The said roller 3 is given an intervallicmovement by means of a train of wheels 0011- necting the same with thedriving-shaft of the machine, as will be hereinafter fully described.The fibrous material, after leaving the curved plate 2 and roller3,passes hetweentheteeth of the comb 4:,secured to the nipper 5. Thisnipper, in combination with another, 6, holds the fibers prior to beinggrasped by the cylinderjaws.

Attached by an arm to nippers 6 is a plate,

7, which serves to disengage the fibers from the comb 4 when the nippersare separated. These nippers 5 6 are attached to arms or levers 8 9,respectively, the lever B being pivoted to arm 9 or secured to shaft 10,and ordinarily held upward by spring 8, attached to said lever and tothe frame-work of the machine, and the arm 9 is secured to shaft 10. Thenipper 5 is drawn down in the following manner: Loose upon the shaft 0is a double finger, F G, the part Fof which abuts against a pin, 8projecting from lever 8, and the part 0 Gr bears a set-screw,g, which isin contact with a finger, I, that is fast upon a shaft, K.

The shaft K has upon one end an arm, L, bearing on its extremity aroller, m,-whose movement is controlled by the revolution of 5 the camN, borne by the driving-shaft 36. This cam is provided with a singleperipheral elevation, so situated as that the roller and the leverbearing it may be raised and the nippers 5 drawn down when said nippersare opposite and in closest proximity to the jaws of the cylinder,whereby the said jaws of the cylinder are enabled to secure a hold uponthe tufts of fibrous material close to the nippers.

Shaft is provided with an arm or lever, 11, having on its extremityroller 12, resting upon a cam, 13, attached to the main shaft, by whichlatter the vertical movementis given to the nipper 5; but in order toallow the jaws of the cylinder to obtain hold upon the fibers, close tothe nippers, and at the same time to give the comb attached to thecylinder oppon tunity to comb out the succeeding tuft of fibers withoutcoming in contact with the nippers, there is also a reciprocal movementgiven to said shafts or levers 8 9 by means of the lever 14, attached toshaft 15, the latter being provided with a lever, 16, having upon itsextremity a roller, 17, engaging with and given motion to by a cam, 18,fastened on the said main shaft of the machine. From this it will beseen that the nippers open, seize the fragments of cotton, and carry thesame forward toward the cylinder, where they are caught by thejaws ofsaid cylinder and drawn from the nippers 5 6 by the rotation of saidcylinder, as will be hereinafter explained. The cylinder 19, lying inclose proximity to the aforesaid nippers, is of hollow construction andconnected by the draft'chamber 20 with a fan. (Not shown.) Upon theperiphery of said cylinder are formed a series of jaws, 21 22, betweenwhich (in their opened position) are the slots 23, so that when thejawsare opened the current of air induced by the aforesaid fan draws in theextremities of the fibers held by the nippers 5 G. The jaw 22 isattached immovably to the periphery of the aforesaid cylinder, but thejaws 21 have an intervallic movement imparted to them in the manner nowdescribed, to wit: The said jaws 21 have upon their extremities flanges24, working in grooves formed in flanges 25 on the cylinder 19.

The flanges 25 are provided with projections or lugs 26, to which arepivoted segmental levers 27, proy ided on their inner ends with arms 28,said arms engaging with a lug on said flanges 24. On their farther orouter extremities are rollers 29, which are raised or lowered by theelevations and depressions of a cam, 30, fixed upon the frame of themachine. This cam is provided with two peripheral elevations, a b, asseen in Fig. 20, so situated as that the rollers 29, in passing overthem, shall raise the levers 27, and so draw the jaws 21 away from jaws22, as the said jaws are successively contiguous to the nippers 5 6 anddelivery-table 43, respectively.

On either side of jaw 21 is an arm, 21, connected by a spring, 21", withthe arm 25 of stated.

the flange of the fixedjaws, and holding the said jaws together when notopened in the manner aforesaid. The intervallic movement of saidcylinder is arranged to correspond with the presentations of the fibrousmaterial in the following manner: Attached to cylinder 19 is a bush, 31,bolted to a plate, 32, hearing a stud, 33. Loosely mounted on said studis a gear wheel, 34, provided with sixty teeth. This wheel gears with apinion, 35, upon the main shaft 36, having'twent-y teeth, and thus thereare three revolutions of the driving-shaft to one of gear-wheel 34.

Secured to the shaft 36 is a second wheel, 37, having forty-four teeth,and this wheel engages with another, 38, provided with thirtythreeteeth, so that the main shaft in making three revolutions causes thestud 33 to make four revolutions, or, finally, 3S revolves four times toonce of 34.

Pivoted to 38 is an eccentric, 39, provided with a strap, 40, bearing onits outer extremity a roller, 41. The latter projects through a radialslot, a, in the wheel 34 and an oblique or inclined slot, 1), in theplate 32. This roller would ordinarily be reciprocated once at eachrevolution ofthe wheel 38; but as the wheel 34 revolves in the samedirection once tofour revolutions of wheel 38, and carries with itroller 41, it will be seen that one of the reciprocating motions will belost. The roller has two motions-a reciprocal and a rotary-and the greatdiameter of the slot 0 in the plate 32 is made to coincide with the pathof the roller resultant from these two motions, so that during one-halfof each reciprocation the roller traverses the oblique slot withoutimparting motion to the plate 32; and as said plate is secured to thecylinder it will be seen that thriceduring each revolution of said platethere is a suspension of motion. This suspension is arranged to takeplace as the nippers and jaws come opposite each other, as hereinbeforeIn the act of being drawn from nippers 5 6 the fibers are descendedupon, divided, and combed by comb A. Said comb is secured to a lever, B,pivoted or journaled at its inner extremity to the shaft 0, (said shaftpivoted to either side of the frame-work of the machine.)

Through the aforesaid lever B a set-screw, E, passes, abutting against afinger, c, the latter fastened securely on the shaft 0. Said shaft bearsupon one extremity an arm, 0, said arm bearing a roller, P, working on acam, 1t, borne by the shaft 42. This cam is provided with a singleelevation, so situated as that the comb may be raised when each new tuftof fibers is presented to the jaws 21 22 and returned to its depressedposition in time to comb the fibers as they are carried away by therevolution of the cylinder. The successive relative positions borne bythe jaws 21 22, the nippers 5 6, and the comb A are shown in Figs. 2 to7, inclusive. Fig. 2 shows the position of IIO IIS

the jaws, nippers, and comb before the tuft of fiber is grasped by saidjaws; Fig. 3, their position at the time of said grasping, Fig. 4, theirposition when the nippers are in the act of releasing the tuft; Fig. 5,their position while being drawn through comb A; and Figs. 6, 7, theirpositions before and while being combed by comb 44, the latter beingoperated as hereinafter described, and the aforesaid comb therebyrhythmically raised and'lowered as the cylinder-jaws are opened andshut. After the fibers have been seized by the jaws 21 22 they arecarried over toward the table 43, while at the same time the next tuftof fibers held by the nippers 5 6 have their outer ends combed by aseries of combs, 44, attached to the cylinder. When the aforesaid tuftarrives at table 43 it is released by the passage of theroller 29 overthe elevation aof cam 30, (where by the lever 27 is raised and jaw 21 isdrawn apart from 22,) and caughtand pushed forward along said table bythe pusher 46, and upon the latter releasing it the vertical movingholder 45 descends upon it and holds it in place till the arrival of thenext tuft, and so on, as the jaws come into line with the top of thetable 43.

The holder 45 is fastened to a curved lever, 47, whose interiorextremities are pivoted to the frame-work of the machine, one of whosesaid extremities is provided with an arm, 48, (upon the outside of saidsupportingfra1ne,) whose outer extremity rests upon a cam, 48 attachedto the shaft 42, provided with a pinion, 48, (said pinion moving theaforesaid feedrollers D D by means of spur-wheel 49, pinion 50, andcog-wheels 51 52,) and a spur-wheel. (Not shown.) On the sameshaft42isawheel, 4S, engaging with a corresponding wheel, 54, on theshaft 55, which meshes with a gearwheel, 54, connecting it with wheel34, and so with the driving-shaft.

Shaft 55 has upon its interior extremity a pinion, 56, gearing withanother pinion, 57, whose shaft drives a train of wheels, 58 59, and apinion. (Not shown.) The latter drives an axle, 61, bearing a circulardisk, 62, to the inner side of which is secured a pin, 62 said pinfitting into slots in awheel, 63, whoseshaft bears a pinion, 64,engaging with a wheel,65, the shaft of the latter bearing the roller 3.By means of the Geneva gearing 62' 62 63 the roller 3 is givenan-intervallic movement, and this gearing is so constructed as to causethe movement of the roller 3 to be synchronous with those ofjaws 21.

The pusher 46 is fastened upon a lever, 66, on whose outer endsarejournaled two rollers, 67, working upon two guides, 68, and whoseinner ends are pivoted upon pins borne by cireulardisks 69. These disksare provided with shafts whose outer extremities bear pinions..

The pinion upon one side gears with wheel 57, upon the other with wheel58. The fibers, after having been push ed forward, as aforesaid,

over the table 43, are caught by the rollers and 71, connected by asuitable train ofwheels with the driving-shaft of the machine, anddelivered into the trough or funnel 72,from which the said fibers areconveyed off to be coiled.

The roller 70 is actuated by a pinion, 73, meshing with another, 74,borne by the shaft of the lower of rollers 71. The opposite extremity ofsaid shaft carries a pinion, 74, meshing with a wheel, 75, upon whoseshaftisa slotted disk, 76. These slots coincide with pins upon acircular disk, 77, borne byshaft 78. Said shaft also bears a cog-wheel,79, which gears with the pinion 35 upon the main shaft of the machine.

The operation of the machine is as follows: The fibers, after passingbetween the ordinary rolls D, are conveyed by the trough l to the curvedplate 2. Here they are forced forward by the roller 3 to the nippers 56, from which (after passing through the comb 4) they are seized by thejaws of the cylinders, drawn through the comb A and passed over to thetable 43, where they are caught and pushed along said table by thepusher 46, and after ward descended upon and held by the holder 45.Subsequently they are released by said holder and pass between therollers 70 71, by which they are forced into the ejectingtrough orfunnelof the machine.
